Fix SMB or refund your customers.
The SMB implementation in SE is unusably broken. Previously no configuration allowed for connecting to a Linux PC in under 20 seconds, like every other file manager for Android I've ever tried (actually they do it in ~1 second). Now, it refuses to connect at all -- "A problem occurred with the network communication."
These issues have been raised and upvoted near 1000 times over a year or two ago and nothing has changed. I'm sick of this piece of shit not working and I regret paying for it when a dozen free apps work better. Fix it or I'm leaving a 1 star review and never buying anything from your company again.

I specifically had bought for SE for it's (past) ability to connect to SMB servers. It's now useless.
